N55 BM3 Stage 2 throttle issues (please help)
So I tuned my 2017 M2 N55 (6MT) to Stage 2 (AGG) using Bootmod3 recently. It ran fine for a couple pulls, but I have gotten a weird issue when shifting where once I depress the clutch, the car automatically revs up an extra ~500rpms. It only happens if I do not rev the car all the way out (shifting at 5k-6k after WOT), but makes shifting quick impossible as i have to wait for the RPM's to drop again. I just replaced the plugs with NGKs gapped 1 step colder, and have tried re-flashing the tune and resetting adaptations. Has anyone else ran into this problem or have ideas on a solution? Any help would be much appreciated.

Here is a pic from a data log, even after I let off the throttle (blue line) the rpm (red line) still climbs for a second or two. Is this normal?

ColbyC123 I think my car was occasionally doing the same thing running the bm3 stage 2 multimap tune, but I was never able to log it before putting the car away for winter. It probably wouldn't hurt to reach out to their support and send over your logs so Halim can take a look at them. That's what I'll be doing if I still notice this happening when I get my car back out. If you do happen to get this sorted out please post an update.
